DESCRIPTION
The throttle actuator is operated by the ECM and opens and closes the throttle valve using gears.
The opening angle of the throttle valve is detected by the Throttle Position (TP) sensor, which is mounted
on the throttle body. The TP sensor provides feedback to the ECM. This feedback allows the ECM to
appropriately control the throttle actuator and monitor the throttle opening angle as the ECM responds to
driver inputs.
HINT:
This ETCS (Electronic Throttle Control System) does not use a throttle cable.
MONITOR DESCRIPTION
The ECM monitors the electrical current through the electronic actuator, and detects malfunctions and
open circuits in the throttle actuator based on this value. If the current is outside the standard range, the
ECM determines that there is a malfunction in the throttle actuator. In addition, if the throttle valve does
not function properly (for example, stuck on), the ECM determines that there is a malfunction. The ECM
then illuminates the MIL and sets a DTC.
Example:
When the electrical current is more than 10 A, or less than 0.5 A and the throttle actuator duty ratio
exceeds 80%, the ECM interprets this as the current being outside the standard range, and illuminates the
MIL and sets a DTC.
If the malfunction is not repaired successfully, a DTC is set when the engine is quickly revved up to a high
rpm several times after the engine has idled for 5 seconds after engine start.
